Officer report

Why officers recommended approval

Officers considered the amendments non-material, acceptable to the highway authority and capable of enabling early studio delivery without prejudicing highway improvements.

“The effect of the proposed changes in this instance are not considered to be material to the approved scheme. The proposed changes are considered to be inconsequential relative to the original approval given the scale of the amendments in the context of the approved scheme. It is not considered that the proposed amendments would disadvantage anyone who was consulted as part of the original application nor would they contravene any adopted policies.”

“The proposed variation to the trigger of Condition 11 would enable the early delivery of the four Sound Stages and supporting accommodation without prejudicing the delivery of the relevant highway infrastructure.”

Officer report

Consultation responses

The Environment Agency had no objections, the highway authority supported the amended condition, and the arboricultural officer had no concerns.

“Name of Statutory Consultee / Other Organisation Comment Environment Agency No objections.. Hertfordshire County Council (Highways Authority) It is agreed by HCC Highways that the amended condition is the best way forward. Hertfordshire County Council (Lead Local Flood Authority) No comments. HCC Growth and Infrastructure No comments TRDC No comments as they will be assessing a duplicate application, which has since been granted consent.”

Officer report

Residents’ concerns

Two objections concerned moving the highway condition, road layout changes and continuing construction affecting residents’ amenity.

“Comments Officer response Objection to move the condition that the roads must be completed before the buildings can be occupied. Concerns also raised with regard to the proposed road layout and changes to the road.”

“Condition 11 was requested by the HCC Highways on the original permission. HCC Highways have agreed that the amended condition is the best way forward and this would also allow for the partial occupation of only 4 of the 11 proposed Sound Stages. Concerns raised with regard to continued construction works taking place and impacting on the resident’s amenity.”
